Maximizing lifetime and coverage for minimum energy wireless sensor network using corona based sensor deployment

Wireless sensor network consist of an enormous range of sensor nodes positioned in any environmental area for collecting and transfer information. These days wireless sensor networks are widely used in different areas of technology, such as health care system, environment monitoring, smart city implementation, military surveillance and many more. To provide a good quality of service it is essential to position the sensor nodes in an effective manner such that the region of interest is fully monitored with minimum number of coverage holes. It is also required to reduce the consumption of energy by the network since the battery lifetime is very limited in the sensor node. This paper presents a Corona based sensor node deployment strategy which provides effective monitoring in WSN. Furthermore it reduces the complete energy depletion of the WSN. Simulation outcomes show that in the proposed strategy the region of interest is fully monitored with low power consumption. Simulation results also demonstrate that network lifetime and coverage can be enhanced to a great extent using proposed corona based deployment.
